Patent CA-2159621-A1 (CA)
Inventor: WAHREN MATS
IPC: F16G13/10
Filed: 1994-05-03
Abstract: The invention relates to an arrangement for a conveyor chain with identical links (A, B, C). These are mutually operatively connected in such a way that two links (A, B; B, C) arranged adjacent to one another are capable of pivoting relative to one another about two mutually orthogonal axes, of which a first axis is perpendicular to the upper surface (1) of the link. The chain is able in this way both to run over a guide pulley and to follow a curved path. In order to permit flexibility in the curved path, gaps (6) are present between the links (A, B, C), the width of which gaps increases up to a certain limit on the convex side of the curved path, and decreases on the concave side as the radius of curvature of the chain path decreases. Each link (A, B, C) has a recess largely parallel with the upper surface (1) and essentially in the form of a slot. Arranged so as to run in which recess is at least one essentially disc-shaped element (8; 8a, 8b), the purpose of which is to cover the aforementioned gaps (6). As relative rotation occurs between two links (A, B; B, C) arranged next to one another, the increased width of the gap occasioned by the relative rotation is covered through an operative connection with one of the aforementioned links (A, B; B, C), and mutual rotation is permitted between the links.

Patent CA-2163571-A1 (CA)
Inventor: ROSEN CARL
IPC: A01M23/02
Filed: 1995-11-23
Abstract: An animal trap includes a housing with a trap door through which an animal to be trapped is thrown.  A throwing mechanism is responsive to the presence of an animal thereon and throws the animal into the housing through the trap door when actuated.  Actuation of the throwing mechanism opens a valve allowing a gas to flow into the housing to euthanize the animal thrown into the housing.  As gas flows into the housing it drives a fluid motor which in turn drives a reset mechanism.  The reset mechanism returns the throwing mechanism to its original set state and closes the valve to inhibit further gas flow into the housing making the trap ready to catch and euthanise another animal.

Title: Concentric annular ring lens designs with minimal angles between adjacent annular ring segments
Inventor: ROFFMAN JEFFREY H
IPC: G02B3/10
Filed: 1996-05-02
Abstract: Multifocal concentric annular ring lens designs are disclosed with minimal angles between adjacent annular ring segments.  The present invention relates in particular to spheric lens designs having different radii of curvature, which enable a numerically controlled (NC) machine to be programmed to machine the adjacent annular segments and the transitions therebetween.  A multifocus, concentric annular ring lens has either a front or back surface which defines a plurality of spherical annular rings having different spherical optical powers with different spherical radii. Pursuant to the teachings of the present invention, the radius of curvature of a first spherical annular  ring is displaced along the longitudinal  optical axis  of the lens relative to the radius of curvature of an adjacent second spherical annular  ring.  The radii of curvature of the first and second spherical annular  rings intersect at a junction whereat the angular difference between tangents thereto at the junction defines a minimal angle to provide a lens having improved wearing comfort and physiological acceptability.

Title: Fluid bearing with compliant linkage for centering reciprocating bodies
Inventor: BEALE WILLIAM T
IPC: F02G1/043
Filed: 1995-03-02
Abstract: An improved mechanical transducer of the type having a body (14) reciprocating in a chamber (3), the body being linked to a housing by a linkage (15) including an axially compliant spring. An anti-friction fluid bearing applies a lateral centering force upon the body and a linkage component of the linkage has a lateral compliance sufficient for the centering forces exerted by the fluid bearing to a least equal the sum of lateral force exerted by the linkage and other lateral forces exerted upon the body. That lateral compliance allows the centering forces of the fluid bearing to be effective in moving the body away from the chamber wall and thereby minimize contact and consequent wear of the interfacing surfaces between the body and the chamber wall.

Title: Method to reduce perceptual contouring in display systems
Inventor: MARKANDEY VISHAL
IPC: H04N5/74
Filed: 1996-10-03
Abstract: A method of pulse width modulation using a spatial light modulator (40) with a finite transition time. The method uses m bits per sample to digitize the incoming data, but apportions the LSB times for pulse width modulation based upon m-1 bits. The current video frame displays all of the bits for each sample, except for the LSBs for each sample. The next video frame displays all of the bits for each sample, adding one more LSB for dividing up the frame time. The first frame could use either the additional LSB time and display no data, or it could use only that number of LSB times it needs. In the latter, the system will have to adjust to different partitions of the frame time for alternating frames. The system includes a spatial light modulator (40), a memory (42), a formatter (48), a sequence controller (44) and a toggle circuit (46), to perform this method.

Abstract: A fiber preform is made solely from a deformable base fiber structure that is initially in the form of a plane plate constituted by superposed two-dimensional fiber plies bonded together by needling. Cuts and/or splits are formed in the base fiber structure, and the preform is made from the cut and/or split base fiber structure by making use of its ability to be deformed.      The structural part is obtained by densifying the preform using a material that constitutes a composite material matrix. It is possible to use a single fiber structure plate which is deformed with the help of splits or cuts so as to obtain the desired preform and in which continuity of the base fiber structure is preserved, or else a plurality of base fiber structure plates can be used which are assembled together by mutual interfitting via the splits or outs, by deforming at least: one of the plates.
